“Waldenstrom macroglobulinemia is a rare slow-growing cancer that affects your blood cells. It’s a type of non-Hodgkin’s lymphoma. (Healthcare providers may refer to this condition by the initials WM or the name lymphoplasmacytic lymphoma). WM happens when genetic mutations change certain blood cells, setting up a chain reaction of medical conditions that may be life-threatening. Providers can’t cure this condition, but they do have treatments that ease and sometimes eliminate its symptoms.”
